I have created a Python file to generate a Mandelbrot set image. The original maths code was not mine, so I do not understand it - I only heavily modified it to make it about 250x faster (Threads rule!). Anyway, I was wondering how I could modify the maths part of the code to make it render one specific bit. Here is the maths part: for...

However, I want to not match spaces that are somehow between quote marks, i.e. apple orange "banana tree" green Should come back as three...
In my Python application, I need to write a regular expression that matches a C++ for or while loop that has been terminated with a semi-colon (;). For example, it should match this: for (int i = 0; i < 10; i++); ... but not this: for (int i = 0; i < 10; i++) This looks trivial at first glance, until you realise that the text betwe...
I have a series of Python classes in a file. Some classes reference others. My code is something like this: class A(): pass class B(): c = C() class C(): pass Trying to run that, I get NameError: name 'C' is not defined. Fair enough, but is there any way to make it work, or do I have to manually re-order my classes to a...

I'm working on an application that will gather data through HTTP from several places, cache the data locally and then serve it through HTTP. So I was looking at the following.

I'm trying to add two images together using numpy and PIL. The way I would do this in matlab would be something like: >> M1 = imread('_1.jpg'); >> M2 = imread('_2.jpg'); >> resM = M1 + M2; >> imwrite(resM, 'res.jpg'); I get something like this: Using a compositing program and adding the images the matlab result seems to be right. ...
I'm tooling around with Django and I'm wondering if there is a simple way to create a "back" link to the previous page using the template system. I figure that in the worst case I can get this information from the request object in the view function, and pass it along to the template rendering method, but I'm hoping I can avoid all this...
Implementing a 'sandbox' environment in Python used to be done with the rexec module (http://docs.python.org/library/rexec.html). Unfortunately, it has been deprecated/removed due to some security vulnerabilities. Is there an alternative? My goal is to have Python code execute semi-trusted Python scripts. In a perfect world, calls to...
Python is pretty clean, and I can code neat apps quickly. But I notice I have some minor error someplace and I dont find the error at compile but at run time. Then I need to change and run the script again. Is there a way to have it break and let me modify and run? Also, I dislike how python has no enums. If I were to write code that ne...
In my python script i am parsing a user created file and typically there will be some errors and there are cases were i warn the user to be more clear. In c i would have an enum like eAssignBad, eAssignMismatch, eAssignmentSignMix (sign mixed with unsigned). Then i would look the value up to print an error or warning msg. I link having t...

A backup of the removed line is already being kept. I would like to do something like file = open('myfile.txt', 'rw+') for line in file: process...
Hello, I've been trying to embed an icon (.ico) into my "compyled" .exe with py2exe. Py2Exe does have a way to embed an icon: windows=[{ 'script':'MyScript.py', 'icon_resources':[(1,'MyIcon.ico')] }] And that's what I am using. The icon shows up fine on Windows XP or lower, but doesn't show at all on Vista. I suppose this is...

Can a regular expression match whitespace or the start of a string? I'm trying to replace currency the abbreviation GBP with a £ symbol. I could just match anything starting GBP, but I'd like to be a bit more conservative, and look for certain delimiters around it. >>> import re >>> text = u'GBP 5 Off when you spend GBP75.00' >>> re.s...
So I am a long time .Net developer looking to branch into something new to further my professional development. I have reduced the next language to learn as one of c++, Python or Ruby and want to hear everyone's thoughts on what I should pick, and why? What trials and tribulations have others found when moving from c# onto one of these...
